// Since there may be many gated pods and they will not move from the

// Scheduling-gated Pods never get schedulable with any events,
// except the Pods themselves got updated, which isn't handled by movePodsToActiveOrBackoffQueue.
// So, here we skip them early here so that they don't go through isPodWorthRequeuing,
// which isn't fast enough when the number of scheduling-gated Pods in unschedulablePods is large.
//
// Note that we cannot skip all pInfo.Gated Pods here
// because PreEnqueue plugins apart from the scheduling gate plugin may change the gating status
// with these events.
